About

//build contains:

Core GN templates and configuration

Core Python build scripts

Since this directory is DEPS'ed in by some other repositories (webrtc, pdfium, v8, etc), it should be kept as self-contained as possible by not referring to files outside of it. Some exceptions exist (//testing, select //third_party subdirectories), but new dependencies tend to break these other projects, and so should be avoided.

Contents

//build/config - Common templates via .gni files.

//build/toolchain - GN toolchain definitions.

Other .py files - Some are used by GN/Ninja. Some by gclient hooks, some are just random utilities.

Files referenced by //.gn:

//build/BUILDCONFIG.gn - Included by all BUILD.gn files.

//build/secondary - An overlay for BUILD.gn files. Enables adding BUILD.gn to directories that live in sub-repositories.
